Names: Michael and Bobby Title: Race to 60! Lab Goal: To figure out how much force it takes to accelerate a car from 0-60 with different amount of weights. Directions: Part 1:In class portion 1. Take a metal track and place it at your lab table and set up a sonic ranger at the end of the track. 2. Place a pulley system at the opposite end from the sonic ranger. 3. Take a piece of string that is a little longer then the length from the sonic ranger to the end of the track and tie a bow at each end. 4. Use a paper clip to secure the string on a track car and put a 100 gram weight on the other end. 5. Let the car accelerate to the end of the track and record the graph in logger pro. 6. Repeat the experiment adding 250 gram blocks on to the track car. 7. Stop repeating after 750 grams are added to the car. Forces: 0 grams added: .69N 250 grams added: .78N 500 grams added: .86N 750 grams added: 1.23N Part 2: Outside Class Portion 1. Take any car you would like and grab 3 other friends. 2. Take 0-60 "g" forces using an accelerometer. 3. Each time you take the force place one more person in the car to add weight. 4. Record data and convert it into force. 5. assume each passenger weighs 150 pounds Data: 0-60 (2 people): .85x9.8=8.33x1763.6= 14690.8N 0-60 (3 people): .82x9.8=8.04x1831.8= 14727.7N 0-60 (4 people): .78x9.8=7.64x1900= 14516.0N
Reflection/Conclusion: We did this experiment to figure out how much force it takes to accelerate a car from 0-60 with different amount of weights. We thought this would be a cool project to do in real life and with a lab set up. We learned that on the lab set up, when a multiple of 250 grams was added, the Newtons of force used to push the cart increased by .9, .8, and .37. We saw similar patterns when we did the real life experiment. This was awesome to see in real life because as we added more people in the car, the force needed constantly and it pretty much imitated our lab experiment.
